Consider the circuits given below: a) In which circuit are the lamps dimmest? b) In which circuit or circuits are the lamps of equal brightness to the lamps in circuit? c) Which circuit gives out the maximum light?

Answer:

The following are the correct answers:

a) The lamps in the circuit (ii) are the dimmest. Because the bulbs are connected in series, lowering the voltage in the rotation.

b) The lamps in the circuit (iii) are of identical brightness. As the bulbs are connected in a parallel configuration and thus get the same amount of required voltage.
